What professor doing with mc is called grooming. Yes, he did asked for the consent from mc and yes, it looks like he cares about mc's opinion and give him a choice. You could say that he is better than ml considering what he did. But the thing is that's what a lot of groomers do. Appear as the most trustable, good person to the victim and manipulate them into choosing him without a second thought. We already know that professor has ulterior motives with the way he acted up to now.
And I'm not saying ml is good compared to professor cause we already that he is a rapist.
